Application filed May 11, 1917. Serial No. 167,893.

To all whom it may concern:

]Be it known that I, SALVADOR TASCA- JRELLA, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Orthopedic Table, of which the following is a full, clear, and exact description.

This invention relates to what may be broadly termed surgical tables, and has for an object the provision of an improved construction especially adapting the construction as an orthopedic table.

Another obje'et'iin view is to provide a table in which certain parts may be raised and lowered while others move back and forth at right angles to the part that is raised and lowered whereby all parts of the patient may; be reached. o

A further object of the invention 1s to provide a bodily movable section for a table which may be moved up and down without interfering with the other parts of the table while the patient is resting thereon.

In the accompanying drawings:

Figure 1 is a perspective view of a table disclosing an embodiment of the invention.

Fig. 2 is a longitudinal vertical sect1on through Fig. 3 on line 2-2. v

Fig. 3 is a top plan view of the table shown in Fig. 1.

Fig. 4 is a top plan view of one end of the table shown in Fig. 3 disclosing the arrangement of slide fitted thereto.

Fig. 5 is an enlarged fragmentary sectional view through Fig. 4 on line 55.

Fig. 6 is a transverse sectional view through Fig. 2 on line 66, the same being on an enlarged scale.

Fig. 7 is a, detail fragmentary horizontal sectional view through Fig. 6 on line 7--7.

Fig. 8 is a detail fragmentary sectional view through one of the swinging bars disclosing certain features of the invention.

Fig. 9 is a section through Fig. 8 on line 9-9.

Referring to the accompanying drawings by numerals, 1 indicates a lower frame which is formed from tubular members of any desired kind, and is provided with uprights 2, 3, 4 and 5, the front uprlghts being connected together by a cross sectlon 6 while the rear uprights are connected by bar 7, as shown in Fig. 2. Suitable wheels 8 are provided at the lower end of each of I the uprights so that the table may be moved from place to place as desired. Side uprights 9 and 1.0 are provided near the center of the frame 1, said side uprights merging into a bracing structure 11, said bracing structure having arms 12 and 13 and a central extension 14 secured to the portion 6, while arms 12 and 13 are connected with the braces 15 and 16 and with the cross bar 17.

Connected to the side uprights 9 and 10 are casings 18 and 19, while the casing 20 is secured to the center upright 21. The casings 18 and 19 contain the gear wheels 22 and 23, respectively, and the worms 24 and 25, respectively, said worms meshing with the wheels 22 and 23 for rotating the same. A shaft 26 extends through the worms 24 and 25 and is rigidly secured thereto, one end of said shaft extending through the slot 27 in the rack bar 28, which rack bar meshes with gear wheel 23 while the opposite end extends through the slot 29 of the rack bar 30, said last mentioned rack bar meshing with gear wheel 22. A hand wheel 31 is connected with shaft 26 so as to rotate the same and move the rack bars 28 and 30 up and down as desired. Casing 20 contains a beveled gear 32 rigidly secured to shaft 26 and a beveled gear 33 rigidly secured'to shaft 34, said last mentioned shaft being supported by the casing and also by a front casing 35 connected with a central upright 36. Shaft 34 is rigidly secured to the worm 37, which worm meshes with the gear 38, said worm and gear being in casing 35 and arranged so that the gear 38 will mesh with the rack 39 while the end of shaft 34 extends through a slot 40 in the rack 39.

By this construction and arrangement it will be seen that when the hand wheel 31 is rotated the racks 28, 30 and 39 are raised and lowered simultaneously according to the direction of movement of the hand wheel so that the parts will be arranged as shown in Fig. 1 or as shown in Fig. 2. By the use of the worms for driving the various parts the movable section 41 connected with the racks will be locked in any position in which it may be left, namely, in a raised or lowered position. It will also be noted that this section is moved directly upwardly and downwardly whereby the same may support part of the patients body or may be removed so that access may be had freely to the parts of the body arranged adjacent said section.

In addition to having the section 41 and arranging the same to move directly up and down, a horizontally movable section 42 is provided and a horizontally adjustable eX- tension or leaf 43 is provided. The leaf or extension 43 is slidingly supported by a cross piece 44 on the front rack 39 and the transverse pieces 45 secured to the section 41. The section 42, however, is an inde pendent member and is mounted upon the rollers 46 and 47, said rollers being arranged on the bars or shafts 7 and 17, as shown in Fig. 2. Guide rails 48 and 49 are provided, as shown in Figs. 2 and 6, said rails inclosing the bars 7 and 17 so as to limit the back and forth horizontal movement of the section 42. It will be noted that the section 42 can move up to but not beyond the end of section 41, while section 41 does not move beneath section 42 nor overlap said section in any manner.

An extension or pivotally mounted leaf 50 is connected to section 42 having suitable ears extending therefrom overlapping ears from the section 42, said ears being provided with openin s through which the rod or shaft 51 exten s, whereby the parts are pivotally connected together on the order of a hinge. A depending bracket 52 is connected with the extension 50 at each end and rests against the angle iron 53 of section 42, as shown in Fig. 2, said brackets carrying a transverse bar 54 designed to accommodate the hook members 55, said hook members being pivotally mounted at 56 on brackets 57, said brackets being secured to the leaf 50. The hook members 55 are each formed with a notch 58 so that the hook members will act as braces for holding the leaf 50 in a horizontal position when the parts are arranged as shown in Fig. 2, but may be removed and permitted to hang down by ravity when the leaf or extension 50 is folded to the dotted position shown in Fig. 2.

In addition to the adjustable sections and leaves described, a pair of upright members 59 and 60 are provided, as shown in Fig. 2, upright 59 being hollow preferably at the upper part so as to accommodate the rod 61 when placed therein. Secured to the upper part of the upright member 59 is a pelvic support 62 which may be held in place in any suitable manner, as for instance, by being threaded into position, said upright having an extension 59 extending above the saddle for ac commodating the sleeve 63, which sleeve is used in some instances, usually when the bar 61 is fitted in the upright 59. As shown in the drawin s, the bar 61 is arranged loosely in the upright 60 and carries at its upper end a number of attachments, as shown in Fig. 1, said attachments being mounted on the horizontal extension 64, the same comprising a fitting 65 slidingly mounted on the extension 64 and an extension 66 having overlapping bars 67 and 68 extending therethrough and carrying hooks or other sup porting members at the ends. These members are designed to receive the upper end of slin s or other supports for certain limbs of the )ody when the section 41 has been lowered. Instead of using the pelvic support 62 a side brace 70 may be substituted, as shown in Fig. 1.

In order to provide means for acting on the feet or the arms. in some instances members 71 and 72 are provided, the detail structure of these members forming no part of the present invention. These members are connected through suitable uprights to the sliding tubular bars 73 and 74, said bars having apertures 75 and 76 designed to register with the apertures 77 and 78 on the sleeves 79 and 80. Pins 81 and 82 are provided for locking the sleeves 79 and 80 to the bars 73 and 74, as shown in Fig. 1. When these bars and members 71 and 72 are not desired the pins 81 and 82 may be removed and the bars telescopically moved inwardly and then turned approximately 180 to the position shown in dotted lines in Fig. 2 so as to be out of the way. The sleeves 79 and 80 have fittings 83 and 84 journaled on the upright 59 so that these sleeves may be swung back and forth. In order to lock these members and parts connected therewith the areshaped member 11 is engaged by set screws 85 and 86 arranged in fittings 87 and 88 secured to the sleeves 79 and 80, said fittings overlapping the member 11, and when the set screws are properly adjusted they will lock these parts together.
